Materials Data on Mn3WO6 by Materials Project

WMn3O6 is Ilmenite-like structured and crystallizes in the trigonal R-3 space group. The structure is three-dimensional. there are two inequivalent W6+ sites. In the first W6+ site, W6+ is bonded in an octahedral geometry to six equivalent O2- atoms. All W–O bond lengths are 1.96 Å. In the second W6+ site, W6+ is bonded in an octahedral geometry to six equivalent O2- atoms. All W–O bond lengths are 1.96 Å. Mn2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Mn–O bond distances ranging from 2.12–2.39 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to one W6+ and three equivalent Mn2+ atoms to form a mixture of distorted edge and corner-sharing OMn3W trigonal pyramids. In the second O2- site, O2- is bonded to one W6+ and three equivalent Mn2+ atoms to form a mixture of distorted edge and corner-sharing OMn3W tetrahedra.

Materials Data on MnWO4 by Materials Project

MnWO4 is zeta iron carbide-derived structured and crystallizes in the monoclinic P2/c space group. The structure is three-dimensional. W6+ is bonded to six O2- atoms to form distorted WO6 octahedra that share corners with eight equivalent MnO6 octahedra and edges with two equivalent WO6 octahedra. The corner-sharing octahedra tilt angles range from 44–56°. There are a spread of W–O bond distances ranging from 1.84–2.13 Å. Mn2+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with eight equivalent WO6 octahedra and edges with two equivalent MnO6 octahedra. The corner-sharing octahedra tilt angles range from 44–56°. There are four shorter (2.17 Å) and two longer (2.28 Å) Mn–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent W6+ and one Mn2+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one W6+ and two equivalent Mn2+ atoms.

Materials Data on MnWO4 by Materials Project

MnWO4 crystallizes in the tetragonal I-4m2 space group. The structure is three-dimensional. W6+ is bonded to six O2- atoms to form corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles are 7°. There is two shorter (1.93 Å) and four longer (1.95 Å) W–O bond length. Mn2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are four shorter (2.12 Å) and two longer (2.67 Å) Mn–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to one W6+ and two equivalent Mn2+ atoms. In the second O2- site, O2- is bonded in a distorted linear geometry to two equivalent W6+ and one Mn2+ atom.
